Abstract (en)

[origin: EP1903680A2] A voltage level converting circuit includes a first transistor (Q1) including a first terminal coupled with a first terminal (31) supplying a first voltage, and a control terminal coupled with an input terminal (35), a second transistor (Q2) including a first terminal coupled with a second terminal (32) supplying a second voltage lower than the first voltage, and a control terminal coupled with the input terminal (35), a third transistor (Q3) including a first terminal coupled with a third terminal (33) supplying a third voltage higher than the first voltage, a second terminal coupled with an output terminal (36), and a control terminal coupled with a second terminal of the second transistor (Q2), and a fourth transistor (Q4) including a first terminal coupled with a fourth terminal (34) supplying a fourth voltage lower than the second voltage, a second terminal coupled with the output terminal (36), and a control terminal coupled with a second terminal of the first transistor (Q1).
